The invention relates to the technical field of biological medicines, in particular to a pharmaceutical composition and application thereof in preparation of a medicine for treating the heart-lung qi deficiency type pulmonary heart disease. The pharmaceutical composition consists of 21-27 parts of astragalus membranaceus, 13-17 parts of semen lepidii, 7-10 parts of cassia twig, 21-27 parts of ligusticum wallichii, 7-10 parts of rhizoma alismatis, 5-7 parts of platycodon grandiflorum and 2-4 parts of Chinese dates. Compared with the prior art, the cassia twig is adopted to replace fructus psoraleae in an original formula, and meanwhile, the medicinal material specifications of the fried semen descurainiae, the raw ligusticum wallichii and the salted rhizoma alismatis are preferably selected. The invention also provides three preparation methods of the pharmaceutical composition, namely a water extraction and alcohol precipitation method, an alcohol extraction and water extraction combined method and a crushing and mixing method. Experimental results show that the pharmaceutical composition has remarkable effects on improving heart functions, lung functions, blood-gas indexes, right ventricular hypertrophy and the like of pulmonary heart disease model animals, meanwhile, the hepatotoxicity risk of fructus psoraleae is avoided, and the pharmaceutical composition has a good clinical application prospect.

The present application relates to the technical field of medical tools, in particular to a multifunctional thrombus suction device, which comprises an outer catheter and an inner catheter movably arranged in the outer catheter, a collecting net is installed at the distal end of the inner catheter, a fixing block and a traction block are arranged on the inner wall of the inner catheter close to the collecting net, a plurality of triangular blocks are arranged between the fixing block and the traction block in sequence, the triangular blocks are provided with first sliding holes penetrating through both sides, the fixing block is provided with second sliding holes aligned with the first sliding holes, a traction wire is arranged in the inner catheter, and the traction wire is fixedly connected with the traction block after sequentially passing through the second sliding holes and all the first sliding holes. The present application solves the problem that most of the current steel wires are basically attached to the inner wall and the sliding of the steel wire is realized through the steel wire hole, thereby driving the adjustment of the bending of the end part. However, the bending adjustment mode has limited adjustment angle, and with the increase of the adjustment bending, the adjustment difficulty also increases, which is not conducive to the bending adjustment in complex blood vessel positions.

A multifunctional blood pressure measuring device comprises a blood pressure measuring body and a body fluid collecting unit. The blood pressure measuring main body is worn on a measured part of a subject and measures blood pressure information. The blood pressure measuring body comprises a tunnel cylinder, and the tunnel cylinder is provided with a tunnel hole for a measured part to penetrate through. The tunnel cylinder comprises a fixed cylinder and a movable cover movably connected to the fixed cylinder. When the movable cover is closed relative to the fixed cylinder, a tunnel hole is defined, and when the movable cover is opened relative to the fixed cylinder, at least part of the measured part is exposed. At least part of the body fluid collecting unit is in operable connection with the blood pressure measuring body, and the body fluid collecting unit pierces the exposed measured part and collects body fluid.

The invention provides an intelligent early warning intervention system for chronic obstructive pulmonary diseases, and relates to the technical field of medical instruments. Comprising a core host, the core host is integrated with an active multi-modal sensor arm and an integrated drug delivery arm, a patient can be actively guided to enter a standardized test posture, and high-quality multi-modal physiological data such as lung function, blood oxygen and breath sound are synchronously collected; an intelligent medicine bin and an automatic delivery mechanism are arranged in the intelligent medicine box, and accurate taking, delivery and auxiliary inhalation of medicine can be completed after early warning is triggered. The standardized seat assists in fixing the sitting posture of a patient through a physical guiding structure, and the wearable monitoring vest achieves respiratory rhythm monitoring and auxiliary sputum excretion. According to the system, all the modules are cooperated through the central controller, and a complete entity closed loop from standard monitoring to intelligent early warning to automatic intervention is constructed. The system effectively solves the problems that household lung function monitoring data is unreliable and intervention is difficult to execute after early warning, and the timeliness, safety and patient compliance of chronic disease management are remarkably improved.

The upper main pipeline is communicated with the upper butt joint; the upper main pipeline is respectively connected with an upper vacuum valve, an upper air valve, an upper water inlet valve and an upper water outlet valve; the lower main pipeline is communicated with the lower butt joint; and the lower main pipeline is respectively connected with a lower vacuum valve, a lower air valve, a lower water inlet valve and a lower water outlet valve. The upper butt joint and the lower butt joint are connected to the upper main pipeline, pressure maintaining stop valves are installed in pipelines of the lower main pipeline respectively, and the upper butt joint is connected with a pressure sensor. According to the utility model, the clamping cylinder is matched with each control valve, so that the flushing machine integrates the functions of clamping, flushing, leak detection and the like, the operation efficiency and accuracy are greatly improved, and the risk and cost caused by quality problems are reduced.

The invention discloses a multifunctional blood compatibility coating for a medical apparatus and a preparation method and application thereof. The coating is formed by copolymerizing a functional monomer containing boron and sulfur elements and a bionic monomer containing phosphorylcholine. Wherein the boron element ensures tough adhesion of the coating on base materials such as plastic and stainless steel, and cooperates with sulfur to realize long-acting anticoagulation; as an active oxygen response unit, the sulfur element endows the coating with intelligent anti-inflammatory and anti-oxidation functions; and the phosphorylcholine structure on the outer layer can effectively resist protein and platelet adhesion. According to the invention, anticoagulation, anti-inflammation, anti-oxidation and strong adhesion functions are integrated, so that the limitation of single function and short-term effectiveness of the existing coating is overcome. The coating is suitable for blood contact instruments such as in-vivo blood sampling devices and intravascular stents, and thrombus and inflammation risks can be remarkably reduced.
